Creating disk groups
NOTE: If you have not created disk groups for a storage array, the Disk Pool Automatic Configuration Wizard is
displayed when you open the AMW. For more information about creating storage space from disk pools, see Disk Pools.
NOTE: Thin-provisioned virtual disks can be created from disk pools. If you are not using disk pools, only standard
virtual disks can be created. For more information, see Thin Virtual Disks.
You can create disk groups either using Automatic configuration or Manual configuration.
To create disk groups:
1. To start the Create Disk Group Wizard, perform one of these actions:
• To create a disk group from unconfigured capacity in the storage array, in the Storage & Copy Services tab, select a storage
array and right-click the Total Unconfigured Capacity node, and select Create Disk Group from the pop-up menu.
• To create a disk group from unassigned physical disks in the storage array — On the Storage & Copy Services tab, select one or
more unassigned physical disks of the same physical disk type, and from the menu bar, select Storage > Disk Group > Create.
• Select the Hardware tab and right-click the unassigned physical disks, and select Create Disk Group from the pop-up menu.
• To create a secure disk group — On the Hardware tab, select one or more unassigned security capable physical disks of the same
physical disk type, and from the menu bar, select Storage > Disk Group > Create.
The Introduction (Create Disk Group) window is displayed.
2. Click Next.
The Disk Group Name & Physical Disk Selection window is displayed.
3. Type up to 30-character name of the disk group in Disk group name.
4. Select the appropriate Physical Disk selection choices and click Next.
You can make the following choices:
• Automatic.
• Manual.
5. For automatic configuration, the RAID Level and Capacity window is displayed:
a. Select the appropriate RAID level in Select RAID level. You can select RAID levels 0, 1/10, 5, and 6.
Depending on your RAID level selection, the physical disks available for the selected RAID level are displayed in Select capacity
table.
b. In the Select Capacity table, select the relevant disk group capacity, and click Finish.
6. For manual configuration, the Manual Physical Disk Selection window is displayed:
a. Select the appropriate RAID level in Select RAID level. You can select RAID levels 0, 1/10, 5, and 6.
Depending on your RAID level selection, the physical disks available for the selected RAID level are displayed in Unselected
physical disks table.
b. In the Unselected physical disks table, select the appropriate physical disks and click Add.
NOTE:
You can select multiple physical disks at the same time by holding <Ctrl> or <Shift> and selecting
additional physical disks.
c. To view the capacity of the new disk group, click Calculate Capacity.
d. Click Finish.
A message prompts you that the disk group is successfully created and that you should create at least one virtual disk before you can
use the capacity of the new disk group. For more information about creating virtual disks, see Creating Virtual Disks.
Locating disk group
You can physically locate and identify all of the physical disks that comprise a selected disk group. An LED blinks on each physical disk in
the disk group.
To locate a disk group:
1. In the AMW, select the Storage & Copy Services tab.
2. Right-click on a disk group and select Blink from the pop-up menu.
The LEDs for the selected disk group blink.
3. After locating the disk group, click OK.
The LEDs stop blinking.
